Precautions to be taken in Gas Tankers with respect to IGC Code

The International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code) provides specific requirements for the safe carriage of liquefied gas cargoes in ships, including gas tankers. 

Here are 10 precautions that should be taken in gas tankers with respect to the IGC Code:

Tank Design: 

The design of cargo tanks should comply with the requirements of the IGC Code, including the materials of construction, insulation, and tank pressure relief systems. The tanks should be designed to withstand the stresses and conditions to which they may be subjected during normal operations, as well as during emergency situations.

Cargo Handling Equipment: 

The cargo handling equipment, including the cargo pumps, hoses, and valves, should be designed and maintained to the standards specified in the IGC Code. The equipment should be capable of handling the cargo safely and efficiently, and should be designed to minimize the risk of leaks or spills.

Ventilation Systems: 

The ventilation systems on board gas tankers should be designed to prevent the buildup of flammable or toxic gases in the cargo spaces. The ventilation systems should be maintained and operated in accordance with the requirements of the IGC Code.

Emergency Shutdown Systems: 

Gas tankers should be equipped with emergency shutdown systems that can be activated in the event of an emergency. These systems should be designed to automatically shut down the cargo pumps, cargo valves, and other equipment in order to minimize the risk of a release of the cargo.

Cargo Measurement Systems: 

The cargo measurement systems should be designed and maintained to the standards specified in the IGC Code. The systems should be accurate and reliable, and should be capable of providing the necessary information to the crew to ensure the safe handling of the cargo.

Training and Drills: 

The crew on board gas tankers should receive specialized training in the handling of liquefied gas cargoes, as well as in the operation of the ship’s equipment and systems. Regular drills should be conducted to ensure that the crew is prepared to respond to emergency situations.

Safety Management System:

Gas tankers should have a safety management system in place that complies with the requirements of the International Safety Management (ISM) Code. The system should be designed to ensure that all aspects of the ship’s operations are conducted safely and efficiently.

Voyage Planning: 

The voyage planning should take into account the specific characteristics of the cargo, including its flammability, toxicity, and reactivity. The voyage plan should also consider the weather and sea conditions, as well as the availability of emergency response resources.

Emergency Response Equipment: 

Gas tankers should be equipped with appropriate emergency response equipment, including fire-fighting equipment, spill response equipment, and personal protective equipment. The equipment should be maintained and readily available in the event of an emergency.

Compliance with Regulations: 

Gas tankers should comply with all relevant international, national, and local regulations and requirements. These regulations may include the IGC Code, the International Maritime Dangerous Goods (IMDG) Code, and local port regulations. The crew should be aware of the specific requirements that apply to the ship and the cargo, and should take all necessary steps to ensure compliance.
